NBC's senior vice president said in an internal memo to staff members Sunday night, "I know we've all been deeply troubled by the revelations of the past 48 hours. Let me be clear — there is simply no excuse for Billy's language and behavior on that tape."

According to several reports, Bush was supposed to address his involvement in the 2005 tape on the "Today" show Monday morning.

The former "Access Hollywood" host issued an apology just hours after the video was published online, saying he was "embarrassed and ashamed."

But that didn't stop people from posting fiery comments on his Facebook page all weekend demanding he resign from the show.
